IMPROVEMENT IN DRESS-PROTECTORS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 172,379, dated January18, 1876; application filed February 20, 1875.

To all whom it may concern:

Be it known that we, ROBERT BLAKE and GEORGE BLAKE, both of the city ofNewark, in the county of Essex and State of New Jersey, have inventednew and useful Improvements in Guards for the Balance Wheels of Sewingand other Machines; and we do hereby declare that the followingspecification, taken in connection with the drawings furnished, is afull, clear, and exact description thereof, sufficient to enable othersskilled in the art to make and use the same.

Our invention relates to the formation and arrangement of a metallicguard or screen adapted to partially inclose the driving or balancewheel, and the crank-pin thereon, of

a sewing or other similar machine driven by a pitman, &c.

The guard, which serves to protect the clothing of the operator fromcontact with the crank connection and wheel, is represented at c in thedrawings, and is made of metal by casting or otherwise. It isrepresented in the drawings in an ornamental form, although it may beconstructed plain. Said guard is represented as attached to the leg of asewingmachine stand by a screw or screws. Yet it may be secured by anyother suitable means. The guard is so located and arranged as to coveror partially cover the front part of the wheel and its connectionsnearest to the location of the operators seat, thereby insuring full andadequate protection to the clothing.

It will be observed that the guard herein set forth and shown is theembodiment of utility, durability, ornamentation, and cheapness, may bereadily adjusted in position, and is not liable to get out of order.

We are aware that devices have been hitherto employed for partiallyprotecting the clothing of the operator of such machines, some of whichhave been formed of cloth, serving as an apron only, while some havebeen made of wood, serving as a basket, etc, which are bulky, andrequire much jvaluable room or space. Such we do not claim; but

Having thus set forth our invention, &c., what we claim as new, andwhich we desire to secure by Letters Patent of the United States ofAmerica, is-

The herein-described metallic guard, made to partially inclose the rimof the wheel, projecting or extending overand covering the pathway ofthe ret'olving crank-pin, as and for the purposes set forth.

In testimony that we claim the foregoing we have hereunto signed ournames before two subscribing witnesses on this the 16th day of December,1874.
